Javadoc

Computes the vector coordinates, for the given x,y texture coordinates and the given cube map face. Also computes the solid angle for those coordinates and returns it. To know what the solid angle is please read this. http://www.codinglabs.net/article_physically_based_rendering.aspx Original solid angle calculation code is from Ignacio Castaño. This formula is from Manne Öhrström's thesis. It takes two coordiantes in the range [-1, 1] that define a portion of a cube face and return the area of the projection of that portion on the surface of the sphere.
